ACTUATORS 1 ACT-45 For further information www.norgren.com Series D Series D cylinders are designed for extremely smooth stroke performance on applications requiring very slow extension and/or retraction speeds. They are identical to the Series SS in design, function and dimensions, but have "ELF" carboxylated nitrile piston seals, rod seals, and rod wipers. "ELF" carboxylated nitrile is a blend of PTFE and other low friction additives that are molded into the substrate of the base seal material. Incorporating this compound in the dynamic seals of the cylinder results in diminished friction, lower breakaway and superior stroke performance. Features: • Extra smooth performance throughout the entire stroke of the cylinder. • NFPA interchangeable. • Cylinders rated to 250 PSI air. 1 Piston Seals: Heavy lip design Carboxilated Nitrile construction, seals are pressure activated and wear compensating for life. 2 Piston: Solid aluminum alloy, light- weight for low inertia, yet strong. 3 Head/Cap/Retainer: Precision machined from solid corrosion-resistant 300 Series stainless steel bar. 4 Rod Wiper: PTFE scraper design for maximum compatibility with wash-down and chemical solutions (FDA-approved material). 5 Rod Seals: Heavy lip design Carboxilated Nitrile construction, seals are pressure activated and wear compensating for life. 6 Piston Rod: 300 Series stainless steel, 40,000 PSI minimum yield, hard chrome plated, ground and polished. 7 Ultra Cushion ® : State-of-the-art design features a unique, one-piece, nitrile compound seal, captured within a precision machined groove. Linear and radial "float" of cushion seal eliminates misalignment. Ultra Cushions provide exceptionally fast "out of cushion" stroke reversal. (Head and Cap Cushions are optional.) 8 Adjustable Captive Cushion Needle Allows for safe and precise adjustment under pressure. 9 Wear Strip: PTFE composite for minimum friction, maximum wear and side load resistance. 10 Tube: Corrosion-resistant 300 Series stainless steel. 11 Tie Rods: High-strength 300 Series stainless steel maintains compression on tube end seals. 12 Lubrication: Permanently lubricated with Magnalube-G PTFE-based grease on all internal components. 13 Rod Bearings: Machined from 300 Series stainless steel, with a PTFE composite wear band insert that eliminates metal-to-metal contact. 14 Acorn Nut: Tie rod threads are covered by stainless steel acorn nuts. 1 2 3 5 4 6 7 9 10 11 8 12 14 13 NFPA Series SS Actuators 1-1/2" to 8" bore sizes
